Suppose the aggregation reorder buffer looks like this:
x-T-R1-y-R2,
where x and y are frames that have not been received, T is a received
frame that has timed out, and R1,R2 are received frames that have not
yet timed out. The proper behavior in this scenario is to move the
window past x (skipping it), release T and R1, and leave the window at y
until y is received or R2 times out.
As written, this code will instead leave the window at R1, because it
has not yet timed out. Fix this by exiting the reorder loop only when
the frame that has not timed out AND there are skipped frames earlier in
the current valid window.

This patch adds to the fix "fix BSS double-unlinking"
(commit 3207390a8b) by Johannes Berg.
It turns out, that the double-unlinking scenario can also occur if expired
BSS elements are removed whilst an interface is performing association.
To work around that, replace list_del with list_del_init also in the
"cfg80211_bss_expire" function, so that the check for whether the BSS still is
in the list works correctly in cfg80211_unlink_bss.

The ieee80211_key struct can be kfree()d several times in the function, for
example if some of the key setup functions fails beforehand, but there's no
check if the struct is still valid before we call memcpy() and INIT_LIST_HEAD()
on it. In some cases (like it was in my case), if there's missing aes-generic
module it could lead to the following kernel OOPS:

commit 86271e460a introduced a
regression that caused mac80211 queues in stopped state.
ath_drain_all_txq is called in driver flush which would reset
the stopped flag and the mac80211 queues were never started
after that. iperf traffic is completely stalled due to this issue.
Restart the mac80211 queues in driver flush only if the txqs were
drained.

With the recent tx status optimization in mac80211, we bail out as
and and when invalid rate index is found. So the behavior of resetting
rate idx to -1 and count to 0 has changed for the rate indexes that
were not part of the driver's retry series.
This has resulted in ath9k using incorrect rate table index which
caused the system to panic. Ideally ath9k need to loop only for the
indexes that were part of the retry series and so simply use hw->max_rates
as the loop counter.
Pasted the stack trace of the panic issue for reference.

("dt/net: Eliminate users of of_platform_{,un}register_driver") we

The NIU driver creates a dummy platform device to represent the
board that contains one or more child NIU devices. Unfortunately
we use the same name, "niu", as the OF device driver itself uses.
The result is that we try to probe the dummy "niu" parent device we
create, and since it has a NULL ofdevice pointer etc. everything

struct aunhdr has 4 padding bytes between 'pad' and 'handle' fields on
x86_64. These bytes are not initialized in the variable 'ah' before
sending 'ah' to the network. This leads to 4 bytes kernel stack
infoleak.
This bug was introduced before the git epoch.

As specified by errata eTSEC49 of MPC8548 and errata eTSEC12 of MPC83xx,
older revisions of gianfar controllers will be unable to calculate a TCP/UDP
packet checksum for some alignments of the appropriate FCB. This patch checks
for FCB alignment on such controllers and falls back to software checksumming
if the alignment is known to be bad.
